Change Of Hospital Gowns?

On Tuesday I had dual endoscopy exams. They went down my throat and up my butt. I was hooked to an IV in my left arm. A BP cuff on my left arm. They pulled my gown down to place heart monitors on me. All this was done before any anesthetic was administered. I distinctly remember the gown I was given to wear. I remember the print design. There were five people in the procedure room. Two docs, two nurses, and a student who I gave permission to observe my procedures. When I woke up and began to become aware; I noticed that I was NOT WEARING the original gown. I know it wasn't. It was a completely different gown with a completely different print. My question is: Would they change the gown during the procedures, before or after? It is obvious during my "out" time I would have been buck naked. Where? For whom? Can anybody explain why this would have been done; and when they would have removed my gown? Do you think they would have used blankets to cover me or just carried on with me au natural? It is a mystery both intriguing and a bit unsettling. Any ideas?

They consider it TWO separate procedures.

They could change the gown between procedures or they may have changed it if the gown got wet or dirty.

They keep you covered, you were never buck naked.

I'll take your word for it considering your background. I just don't understand the feasibility of such a unique change.

Are you concerned that they saw your body?

They probably changed the gown because it got something on it. Having down many endoscopies and colonoscopies I can tell you that we don't like to see a patient naked. They get cold and we respect their privacy. A sheet would have covered you and it was probably changed by a nurse

Nurses want everyone to respect their patients privacy. Personally I like to see patients in gowns. I'm not embarrassed obviously as a physician, I'm just worried about the patients privacy and getting cold.
